Environmentally-friendly jean crack slurry and crack jean fabric making method

Abstract

The invention discloses an environmentally-friendly jean crack slurry and a crack jean fabric making method. A building type material is used in the slurry, and the slurry is sheet in shape after sun crack, can easily shred from a material and does not influence the treatment of a next operation of a jean product. A waterproof agent is also introduced into the crack slurry in the invention, so the working solution adsorbing amount of the slurry in the processing process is reduced to reduce wastes, and an oxidation reagent attached to the slurry naturally returns to a processing container in the processing process to reduce the pollution of the adherence of a large amount of KMnO4 or H3PO4 in the waste slurry to the environment.

Description

technical field [0001] The invention belongs to the field of textile processing, in particular to the field of processing denim fabrics. Background technique [0002] The crack processing of denim fabric is through special processing, so that the surface of denim fabric shows a white pattern consistent with the cracks. Ice cracks are a very typical incomplete beauty that turns decay into magic. Cracked denim fabrics emerged around 2006, and now they have spread to all denim washing centralized processing areas across the country. [0003] The way of crack processing on denim fabrics currently has the following major defects: [0004] First, the processing temperature of wax treatment is difficult to control, the wax removal process is cumbersome, the number of times of watering is too high, and the wax is not easy to remove. According to production statistics, wax is used as the base material for cracks. Taking 25 pairs of jeans as an example, the wax removal The process n...

Problems solved by technology

[0004]First, the processing temperature of wax treatment is difficult to control, the wax removal process is troublesome, the number of times of water passing is many, and the wax is not easy to remove. According to production statistics, wax is used as a For cracked substrates, take the processing of 25 pairs of jeans as an example, 500L of water needs to be used in the wax removal process, and 5kg of Na2CO3 and 2kg of washing powder must be put in at the same time, and After cleaning, there will still be a small amount of wax remaining on the fabric, which will affect subsequent processing

[0005]Second, the main component of the existing cracked slurry is the potassium salt / calcium salt of arabic acid, and then it is mixed with printing paste, and printing paste is generally used Starch is used as the base material. Due to the hydrophilicity and instability of starch, it is prone to mildew or hydrolysis, resulting in a short shelf life of the slurry (about 3 months); Absorb a large amount of working fluid (including the mixed solution of KMnO4 and H3PO4), which reduces the utilization rate of the working fluid, and even There will be a problem of infiltration at the edge of the crack, resulting in unstable product quality; and, the waste slurry after processing is generally directly landfilled without any treatment, and KMnO4 and H3 are adsorbed PO4 slurry will permeate into groundwater with rainwater after landfill, causing secondary pollution to water resources
